The aim of this study was to evaluate how the oral health of adolescent influences the quality of their lives. A descriptive cross-sectional study was realized, with a sample of adolescent students aged between 12 and 15 years, from the city of Ibirataia and district of Cotton on the state Bahia, Brazil, who completed a validated questionnaire, the Oral Health Impact Profile (OHIP-14). It was observed a general average of 4,97 for the total score of the OHIP-14. The areas with the highest and lowest average were physical pain (1,16) and functional limitation (0,43), respectively. Most respondents reported some impact of oral conditions on quality of life (90,00%), however, most of these reported low impact (74,28%). Other 15,70% reported a average impact and 9,99% no impact. There were not reports of major impact.The oral health impacted the quality of life of most teenagers, although this impact has been weak. This suggests that, even if present in the daily activities of adolescents participating in this study, it does not cause major effects on the quality their lives. The physical pain and psychological distress were the most prevalent areas.
